FRED KLAUS, OF CHICAGO, ILLINOIS.

PRESS FOR CANS.

SPECIFICATION forming part of Letters Patent No. 722,853, dated March17, 1903.

Application filed April 19, 1901. Serial No. 56,532. (No model.)

To all whom it may concern- Be it known that I, FRED KLAUS, a citizen ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inPresses for Cans; and I do here-by declare the following to be a full,clear, and exact description of the invention, such as Will enableothers skilled in the art to which it appertains to make and usethesame.

My invention'relates to a novel press for cans adapted to be used inforcing the air out of a can in the process of preserving corned beefand the like, the object being to provide a simple portable press forthis purpose; and it consists in the features of construction andcombinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating I my invention, Figure 1 is avertical central section of a press made in accordance with myinvention, showing a can in position to be operated upon. Fig. 2 is ahorizontal section on line 2 2, Fig. 1.

In said drawings, A represents a tapered rectangular can, such as iscommonly used in which to preserve corned beef.

My press consists of the rectangnlarframe B, adapted to be supportedabout the middle of the height of said can on the legs C. Said framecarries the blocks D and E on its inner surface, which are rectangularin shape and nearly as large as the side of the can they are adapted tooperate upon. Two similar blocks F and G are adjustably mounted on saidframe B, being adapted to be adjusted by means of the screws H, whichare mounted in the side members of said frame. Pins I are rigidlymounted on said members F and G, adapted to slide freely through holesin said frame B, and are designed to hold said members F and G in theirproper relative positions. Said blocks D, E, F, and G are convex ontheir sides, which are adapted to operate on said can and are adapted toforce the sides of said can inwardly, and thus make the internal volumeof said can smaller.

In using my'device the can is first filled with the rbeef through theopening J in its top, after which the cover K is soldered in place, asmall hole L being left in said cover. The can is then immersed inboiling water until the contents are fully cooked, during which processthe pressure generated within the can forces the sides of same outbeyond their normal position. It is then removed and placed in thepress. The screws H are then operated, and the sides of the can arepressed inwardly, thus forcing the sides of said can back to or .beyondtheirnormal position against the pressure within same, and thusexpelling any air which may remain in said can, the squeezing processbeing continued until juice or water is forced out through said hole L.Said hole is then closed by means of a drop of solder before the can isremoved from said press.

I claimas my invention- In a device of the character described, thecombination with a rectangular frame, of a pair of rectangular blocksrigidly secured to one of the sides and ends respectively of the frame,a pair of adjustable rectangular blocks mounted at the other side andend of the frame, screws mounted in the frame and having their innerends in engagement with the said adjustable blocks, and a pair of'horizontally-disposed pins rigidly secured to each of the saidadjustable blocks, and slidably mounted in openings in the adjacent sideand end respectively of the frame, said blocks having convexedinnerfaces, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

FRED KLAUS.
